+Running in offline mode (Optional)
+----------------------------------
+
+Maven is used to build and run ONOS. 
+By default, maven tries to reach the repositories.
+To suppress this behavior '-o' option should be given to `mvn` command.
+
+To give additional option to `mvn` commands used in ONOS, 
+use the MVN environment variable.
+
+* Example: Running in offline mode
+
+    $ env MVN="mvn -o" ./start-onos.sh start
